The Marblemelon Plant is a terrestrial life form belonging to the flora category. By using a Survival Knife, the player can harvest Marblemelon Seeds from Marblemelons. Marblemelons can be eaten for water and nutrition, and is a pretty good (but inefficient and tedious) food source when farmed. Once planted from seed, the Marblemelon will take 800s (13m:20s) to mature.

The popular belief that Marblemelons are the best food in Subnautica is incorrect. For a detailed calculation of the food/water value of Bulbo Trees compared to Marblemelons, read the main Bulbo Tree article.

Melons can be found planted in abandoned Growbeds and other planters in and around the three component parts of the Degasi Seabase on the Floating Island.


The Marblemelon Plant appears to share many similar features with watermelons found on Earth, like its stripes and shape. However, it is yellow in color with dark brown stripes, and it has small lumps on its surface. It also features large dark green palm-like leaves branching out from its top. It also bears a resemblance to a marble, due to it being round and having colorful stripes.
